8"diameter crowned drive wheel for 2x72 belt grinders. Lightening cuts are machined into the front and back of the wheel to make it the lightest aluminum 8" drive wheel on the market. Benefits of lightening cuts to reduce weight equals less rotational mass for faster start ups and decreased loss of power giving you more power to apply for grinding. The wheels are crowned to provide stable belt tracking. The 8 inch drive wheel is great for direct drive set ups with a 1725 RPM motor to achieve a higher SFM. The 8" diameter increases the surface feet per minute (SFM) by 100% over a 4" drive wheel. A 1725 RPM motor will run at approximately 3600 SFM and a 3450 RPM motor will run approximately 7200 SFM. If you run a higher rpm motor like a 3450 rpm make sure the rest of your wheels can handle the speed. An 8" drive wheel on a 3450 rpm motor will spin a 2" diameter wheel at 13,800 rpm.
